To create B as a 3 by 3 by 5 byte array where each element is set to a random value, enter:
Result = BYTARR( D1[, ..., D8] [, /NOZERO] )
This function returns a byte vector or array.
Either an array or a series of scalar expressions specifying the dimensions of the result. If a single argument is specified, it can be either a scalar expression or an array of up to eight elements. If multiple arguments are specified, they must all be scalar expressions. Up to eight dimensions can be specified.
Normally, BYTARR sets every element of the result to zero. If the NOZERO keyword is set, this zeroing is not performed (array elements contain random values) and BYTARR executes faster.
